Laser range finder protection device

Abstract

The invention discloses a laser range finder protection device. The device comprises an air inlet cover arranged outside a laser range finder in a covering mode and an air curtain pipeline installed at a front end of the air inlet cover. Cooling air can circulate in the air inlet cover, and when the air in the air curtain pipeline flows out of the air curtain pipeline, a dustproof air curtain canbe formed at an air outlet channel at the front end of the air inlet cover. According to the laser range finder protection device provided by the invention, through the design of a dust cover and theair curtain pipeline, the laser range finder is cooled and dedusted, positioning accuracy of the laser range finder is ensured, a maintenance period of the laser range finder protection device is prolonged, and safety guarantee is provided for automatic tapping.

Description

technical field [0001] The invention relates to the protection field of a laser range finder, in particular to a protection device for a laser range finder. Background technique [0002] When tapping steel in steel mills, the automatic tapping system is generally adopted. Through comprehensive detection methods, combined with mathematical models and automatic control technology, the automatic tilting of the converter and the automatic follow-up of the ladle car are realized to achieve the automation of the tapping process. In the actual automatic tapping process, the follow-up function of the ladle car depends on the accuracy of the positioning system of the ladle car, which directly determines the success or failure of the automatic tapping. [0003] During the movement of the ladle car, a laser rangefinder is generally required for position detection. In the prior art, the air intake cover of the laser rangefinder generally has the problem that the mirror surface of the ra...

AI Technical Summary

Problems solved by technology

[0003] During the movement of the ladle car, a laser rangefinder is generally required for position detection. In the prior art, the air intake cover of the laser rangefinder generally has the problem that the mirror surface of the rangefinder is easy to be stained with dust. The value of the laser rangefinder has no effect, but in special environments (such as: near ladle trucks and slag trucks), slag falling and splashing are frequent, accompanied by a large amount of dust. At this time, the front end of the laser rangefinder cannot be protected. It is easy to cause a large amount of dust accumulation on the mirror surface, which seriously affects the positioning accuracy of the laser rangefinder and shortens the maintenance cycle
